BRASILIA, Aug 21 (Reuters) - Brazil’s state-run power company Centrais Eletricas Brasileiras SA (Eletrobras) said on Tuesday its board had approved the terms of sales of stakes in 71 special purpose entities in an auction slated for Sept. 27.

Eletrobras said in a securities filing the auction would comprise 18 lots and was part of a debt reduction plan approved last year. It did not give details on the assets held by the entities. (Reporting by Jake Spring; editing by David Evans)
